2020 Online Registration & FAQ’s

Thanks to APBA HQ, we are having ONLINE registration! We want to stress that online registration is highly encouraged if not required. Minimal contact is the new thing! Here’s how to register online;

You must click the Entry Blank button and follow all directions. This entry blank also serves as your liability waiver. You may pay online with a credit card – if you do not wish to do this, you may pay at the pits with check or cash. Please do not forget to fill out your three crew members. These are the three people you get to bring with you into the pits. These three people need to sign the General Liability Waiver below.

Entry Blank Form

ONLY CREW SIGNS THIS ONE! No drivers. No more than three crew members. These members also must be listed on your entry blank. Click the General Liability button and make sure it’s filled out by each crew member separately. Minors must be filled out at the pits in person.

2020 Frequently Asked Questions

COVID-19 & Top O’ 2020


Is there a race this year?

Are spectators allowed in the pits (DeVoe Beach)?

Will you be monitoring people, racers, spectators, etc. that try to come into the pits?
Yes, very strictly. We cannot let more than 500 people in and we will be tracking this.

FYI to all racers – only three crew/family members are allowed into the pits with you. Please plan accordingly. This is due to the Governors Executive Order limit of 500 people for an outdoor sport gathering.

Are masks required?
Please see the above COVID Top O’ safety plan PDF!

When can I bring my trailer into the pits?
3-4 pm

Do I have to go to registration on Friday night even if I registered online?
Yes. There is an informational packet that will have quite a bit of important material in it. You want tow money, don’t you!?

Will there be food?
Yes, there will be a food truck!

Are there going to be t-shirts?
Yes! We just aren’t printing as many.

Will there be parking in the pits for cars (this does not pertain to trailers)?
Maybe! This depends on how many racers we have register. If we have lots of entries, we may have to park trailers in the parking lot. If that happens, we won’t be allowing people, racers, even board members to park their cars in the parking lot. As always, you can drop off materials, coolers, etc. and then move your car afterwards. Please plan accordingly!

Will there be awards?
Yes. After scores are finalized, pits are cleaned, and obviously weather dependent. Awards will be at the pits. Food truck is staying later as well. We anticipate 4/4:30 pm.
